Bees have teeth!

So...., after telling people for years that bees only sting, they don't bite, apparently bees can bite, they chomp on parasites and the like, inject their victims with some stuff that paralyses them.

This article below is lifted directly out of the BBC website, I hope they don't mind, and here is a link as well:

The varroa mite is endemic throughout both feral and cultivated honey-bee colonies (...but not here..... yet!).The pests that honey-bees bite include varroa mites as well as wax moth larvae.

Honey-bees are known for their sting, but scientists have now discovered they can also bite.
Bees resort to biting when faced with pests, such as parasitic mites, that are too small to sting.
Close study of the biting behaviour has revealed that they secrete a chemical in their bite that stuns pests so they are easier to eject from a colony.
Tests suggest the chemical could also have a role in human medicine, as a local anaesthetic.
Stun tests
Dr Alexandros Papachristoforou, a biologist at Greece's Aristotle University of Thessaloniki told the BBC honey-bees had previously been seen dealing with pests that lived alongside them in colonies but this had always thought to be part of their grooming behaviour.
"Everybody thought that was it. Full stop," Dr Papachristoforou said. "But that's not the case. It's something totally different and was just there and we could not see it.
"I think we know too many things about the pathology of honey bees," he said. "We are still missing a lot of basic knowledge on their biology and behaviour."

If the population of mites in a hive is left unchecked they can sap the strength of workers, making them much more susceptible to viruses, disease and other debilitating conditions.
Wax moth larvae burrow through the comb in hives gradually destroying the cells where broods are raised and honey stored.
The knock-out effect of the chemical secreted in the honey-bee bite, known as 2-heptanone, was discovered as Dr Papachristoforou and colleagues observed bees dealing with pests.
Dr Papachristoforou recovered wax moth larvae that had been ejected from a hive, assuming the bees had killed them. Instead, he said, the larvae had started wriggling again soon after being ejected.
Before now bees were thought to secrete 2-heptanone as an alarm pheromone to tell other colony members about a potential threat.
However, said Dr Papachristoforou, this had never seemed an entirely satisfactory explanation because 2-heptanone was so volatile that it quickly lost its potency. In addition, he said, bees had at their disposal a much more powerful chemical alarm signal.
To stun pests, the 2-heptanone is injected at the site of the bite a bee inflicts on a mite, moth or larvae.
Early tests suggest 2-heptanone may also find a role in humans as a local anaesthetic. It could be an alternative to well established treatments such as lidocaine that can provoke allergenic reactions in some people.The researchers published their results in the journal Plos One.
"The potential implications of this new research for honey-bees and their interactions with varroa mites and wax moth larvae will need to be looked at in more detail, but the initial results look really interesting," said Giles Budge, senior researcher with the UK's National Bee Unit.
"I think it is amazing that despite all the years of intensive study there are still massive discoveries to be made about fundamental honey-bee physiology such as the ability to paralyse small insects and mites," he said.
Dr Papachristoforou, said the good news about the research was that bees would not inflict any damage on humans if they bit them.
"Humans cannot be bitten by bees," he said. "They have such small mandibles they can only use them against larvae and mites."

....and here's a bee tooth to prove it (lifted of the papers website, linked above):

  1. Hi Jonas! Do you know how long it takes a swarm to get brood?
    I caught a swarm a week ago, checked the hive today, very busy lots of comb and nectar, saw the queen but couldn't see any brood???
    Puzzled!! It could have been a virgin on swarming...Any advice??

  2. Hey Gilian,
    the queen in the swarm is the old queen from the old hive, so that means she is already fertilised, and should be good to go. Maybe a bit tired, or old, and possibly not in peak condition. And a bit Kranky. Assuming it takes a day or two for her minions to build cells, it then takes 9 days until you get capped brood, so you should have something to look at in the next few days...?

    If not, you are possibly in trouble, you may not have a queen in there, it will descend into drone-rearing, and slowly collapse.
    Good luck, and thanks for the question, any time.

    I find it amazing that when you re-queen, (say with a pre-fertilised queen from queensland...), the entire genetic makeup of the hive changes over in the next couple of months...
